Depend on what you use the acrylic for.  MANY years ago (1970 or so) at 
the Lawrence Radiation Lab, we used a pair of massive acrylic beams  (2" 
thick, 24" wide, 10ft long) to support a 3MV Cockroft -Walton 
generator.  Wiped them down with alky before sealing them in the HV 
pressure vessel, then had to replace the entire assembly because of 
stress cracks.  If it's not a structural element, you're probably safe.
